Indications for Use
MOSAIQ is an image-enabled electronic medical record system (EMR) used for oncology workflow management. It lets users: Supply electronic patient charts and assemble care plans, order diagnostic tests, and prescribe medications. Import, view, annotate, manipulate, enhance, and archive images. Import, keep, and export information related to patient treatments to monitor treatment progress from a central location. This includes orders, documents, lab information, and other related information from compatible programs. Generate and keep medication and formulary lists and calculate applicable medication dosages for medical oncology. Design leaf plans for operation with radiotherapy treatment machines that have multileaf collimators. Users can give, view and change geometric data related to treatment fields, including the MLC accessory. Ensure plans imported from treatment planning systems agree with treatment machine constraints. Additionally, MOSAIQ: Supplies other administrative functionality necessary to operate medical and radiation oncology departments. Shows reference images for setup purposes, refers to predefined settings to help treatment machine setup, and tells clinicians of necessary steps before treatment. Reads actual settings from the treatment machine through the machine's communication interface. It compares these settings with predefined values. If a mismatch occurs between the planned values and the actual machine settings, the system inhibits treatment. Verifies the actual treatment against radiation treatment plans. At applicable points during the treatment, it records the actual delivered values to provide treatment tracking.
Device Story
MOSAIQ is an integrated oncology information system (OIS) for medical and radiation oncology. It functions as an image-enabled EMR for workflow management, care planning, and documentation. For radiation oncology, it imports treatment plans, designs multileaf collimator (MLC) leaf shapes, and performs verify-and-record functions. The system interfaces with linear accelerators to read machine settings, compares them against planned values, and inhibits treatment if a mismatch is detected. It records delivered treatment parameters for the patient record. Used in clinical settings by oncology staff; it centralizes patient data, including lab results and medication lists. It calculates medication dosages for medical oncology. By automating verification and record-keeping, it reduces the risk of treatment delivery errors, ensuring that radiation delivery aligns with the prescribed plan, thereby enhancing patient safety.
Clinical Evidence
No clinical trials were performed. Bench testing was conducted using simulated clinical workflows and actual patient data to validate system functionality and safety. The device was deemed fit for clinical use based on this bench testing.
Technological Characteristics
Integrated software suite for oncology management. Includes image processing (ViewStation), MLC leaf shape definition (MLC Fit), and treatment machine interface/verification (SEQUENCER). Operates as an EMR with connectivity to radiotherapy treatment machines via communication interfaces. Software-based verify-and-record functionality. Major level of concern due to interface with radiation delivery systems.
Indications for Use
Indicated for information flow support in healthcare facilities where radiotherapy and/or chemotherapy are prescribed. Medical oncology dose calculation functions indicated for patients 18 years or older. Not intended for diagnosis.

### MOSAIQ INDICATIONS FOR USE
MOSAIO supports information flow among healthcare facility personnel. It can be used wherever radiotherapy and/or chemotherapy are prescribed. MOSAIQ is not intended for use in diagnosis. Medical oncology dose calculation functions are designed for use with patients 18 years or older only.
### DESCRIPTION OF THE PRODUCT
MOSAIO is a multi-functional, integrated software suite that forms a comprehensive electronic oncology management system for medical and radiation oncology facilities. For both medical and radiation oncology users. MOSAIO provides image-enabled electronic patient charting and record management as well as medical transcription and billing functionality. For radiation oncology users, it also includes the ability to import and export radiation treatment plan information, the ability to plan multileaf collimator (MLC) shapes, and verify and record treatment setup and delivery.
Previously, three of the components within MOSAIQ were cleared through the 510(k) process individually. The ViewStation software (K011694) provides the ability to to import, view, annotate, manipulate, enhance, manage and archive medical images and includes patient positioning functionality. The MLC Fit software (K991133) allows users to define MLC leaf shapes for radiation treatment plans. The SEQUENCER software (K981313) connects to the treatment unit (e.g. linear accelerator) and compares its setup
{3}------------------------------------------------
to the predefined treatment field in the treatment chart. SEOUENCER inhibits treatment if errors are detected, records actual treatment unit parameters, and allows this information to be stored and/or printed as part of the treatment record.
MOSAIQ includes the ViewStation, MLC Fit and SEQUENCER software applications as well as other applications that were not classified as medical devices when considered as individual products. This section of the Premarket Notification provides a description of the functional units within MOSAIQ.
#### LEVEL OF CONCERN
Because MOSAIQ includes many different pieces of functionality, we conclude that the level of concern for the device as a whole must be equivalent to that of the function with the highest level of concern, namely, the verify and record functionality.
The FDA guidance document entitled "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices," issued May 11, 2005, Table 1, item 4b states, "Does the Software Device control the delivery of potentially harmful energy that could result in death or serious injury, such as radiation treatment systems....."
The record and verify function within MOSAIO does not directly control the machine that delivers the radiation. However, it does interface with the linear accelerator and is responsible for detecting potential mismatches between planned and actual machine settings and alerting the user. Thus, it is a major level of concern function.
#### SUMMARY OF CLINICAL TESTING
Clinical trials were not performed as part of the development of this product. Clinical testing on patients is not advantageous in demonstrating substantial equivalence or safety and effectiveness of the device since testing can be performed such that no human subjects are exposed to risk. Bench testing was performed, as described in Section 16.8, using simulated clinical workflows and ad hoc testing where appropriate, with actual patient data. The product was deemed fit for clinical use.

Two short videos show you everything — or skip straight to the written tutorial if you'd rather read. You can reopen this any time from the Tutorial button in the top bar.
Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
